• Name for build option (for "make install") specifying where to install web application

  - by Jakub Narebski

  I want to provide 'install' target for Makefile for web application. I'd like to be able to install it, for example like described below: $ make install \ xxxdir=/var/www/cgi-bin (similarly to how one would use 'bindir' for ordinary programs, and 'mandir' / 'infodir' for documentation). Is there any standard (similar to autotools 'bindir', 'sharedir', etc.) for the name of 'xxxdir' variable in above example? How do you think should such build configuration variable be named?

• Passing values from UIButton to an UIActionSheet

  - by Michael

  I'm trying to send an ActionSheet a variable from a button. I can't use the tag property because its being used for something else. I've declared myIndexRow as an instance variable and have: NSInteger myIndexRow = indexPath.row; [deleteButton addTarget:self action:@selector(showDeleteSheet:) forControlEvents:UIControlEventTouchUpInside]; deleteButton.myIndexRow = myIndexRow; but I'm getting the 'Request for member 'myRow' is something not a structure or union' There is something obvious I am missing here.

• PHP/HTML Strange refresh problem

  - by user270797

  After I upload my PHP files to my web host, I view the page by the URL. So what I usually do as I work on the page is make a change, upload, then refresh the browser to view my changes. What I find is that sometimes I refresh and it shows me a previous version of the page, I hit refresh 5 times and it shows me 5 different versions of the page some old changes some new changes, it makes it really difficult to know which is the latest version. I dont think this is a local caching problem, Ive disabled caching in all browsers, the problem occurs in IE, FF, Chrome I have a feeling it might be the web server. I believe the hosting company uses Zeus (?) web server product.

• Calling and writing jquery/javascript functions

  - by Ankur

  I think I have not got the syntax correct for writing a javascript function and calling it to assign its return value to a variable. My function is: getObjName(objId){ var objName =""; $.ajax( { type : "GET", url : "Object", dataType: 'json', data : "objId="+objId, success : function(data) { objName = data; } }); return objName; } I am trying to call it and assign it to a variable with: var objName = getObjName(objId); However Eclipse is telling me that "the function getObjName(any) is undefined"

• Combining Session and Cache

  - by Zyphrax

  To make my extranet web application even faster/more scalable I think of using some of the caching mechanisms. For some of the pages we'll use HTML caching, please ignore that technique for this question. E.g.: at some point in time 2500 managers will simultaneously login on our application (most of them with the same Account/Project) I think of storing an Account-cachekey and Project-cachekey into the user's Session and use that to get the item from the Cache. I could have simply stored the Account into the session, but that would result in 2500 of the same Accounts in memory. Is there a better solution to this or does it make sense :)?

• Why would var be a bad thing?

  - by Spoike

  I've been chatting with my colleagues the other day and heard that their coding standard explicitly forbids them to use the var keyword in C#. They had no idea why it was so and I've always found implicit declaration to be incredibly useful when coding. I've never had any problems finding out what type the variable was (you only hover over the variable in VS and you'll get the type that way). Does anyone know why it would be a bad idea to use the var keyword in C#?

• Effect of 'myObj = [[[[MyClass alloc] init] autorelease] retain];'?

  - by filipe

  I've just downloaded the Facebook iOS SDK and I noticed that in the sample code that comes with the SDK whenever it creates an instance of the Facebook class it does it like this: _facebook = [[[[Facebook alloc] init] autorelease] retain]; where _facebook is a member variable of the calling object (i.e. not a local variable). Can anyone explain exactly what's the point of autoreleasing and then retaining it?

• HTML_Template_IT and wordpress

  - by David Ryder

  I want to use PEAR's HTML_Template_IT in one of my Wordpress page templates so I can separate the HTML from the PHP. I got it working, except I am not sure about one thing. Wordpress's built-in function get_header() actually echo's HTML - so I can't technically set it as a template variable. Is this considered acceptable or is there another way to put the contents of get_header() in a variable? Thanks!

• Will the Order of my Associative Array be maintained from PHP to Javascript?

  - by Colin

  In PHP I'm running a mysql_query that has an ORDER BY clause. I'm then iterating through the results to build an associative array, with the row_id as the key. Then, I'm calling json_encode on that array and outputting the result. This page is loaded with AJAX, and defined in a Javascript variable. When I iterate through that Javascript variable, will I still have the order that was returned from the mysql_query?

• How to combine a list of choices to determine which select statement

  - by Larry

  I have a mysql db and am using php 5.2 What I am trying to do is offer a list of options for a person to select (only 1). The chosen option will cause a select, update, or delete statement to be ran. The results of the statement do not need to be shown, although, showing the old and then the new would be nice (no problems with that part tho'.). Pseudo-Code: Assign $choice = 0 Check the value of $choice // This way, if it = 100, we do a break Select a Choice:<br> 1. Adjust Status Value (+60) // $choice = 1<br> 2. Show all Ships <br> // $choice = 2 3. Show Ships in Port <br> // $choice = 3 ... 0. $choice="100" // if the value =100, quit this part Use either case (switch) or if/else statements to run the users choice1 If the choice is 1, then run the "Select" statement with the variable of $sql1 -- "SELECT .... If the choice is 2, then run the "Select" statement with the variable of $sql2 --- SELECT * FROM Ships If the choice is 3, then run the "Select" statement with the variable of $sql3 <br> .... If the choice is 0, then we are done. I figured the (3) statements would be assigned in php as: $sql1="...". $sql2="SELECT * FROM Ships" $sql3="SELECT * FROM Ships WHERE nPort="1" My idea was to use the switch statement, but got lost on it. :( I would like the options to be available over and over again, until a variable ($choice) is selected. In which case, this particular page is done and goes back to the "Main Menu"? The coding and display, if I use it, I can do. Just not sure how to write the way to select which one I want. It is possible that I would run all of the queries, and other times, only one, so that is why I would like the choice. An area I get confused in is the proper forms to use such as -- ' ' " " and ...?? Not sure the # of options I will end up with, but it will be more than 5 but less than 20 / page. So if I get the system down for 2-3 choices, I can replicate it for as many as I may need. And, as always, if a better way exists, I am willing to try it. Thanks again... Larry
